[texts]Simulation and Analysis of Control Strategies for DSTATCOM
Reactive power and supply unbalance  compensation in power distribution network is a key factor in improving quality at user end. Further, the control techniques applied to the DSTATCOM play major role in its performance. A Distribution STATic COMpensator (DSTATCOM) has been proposed for compensation of reactive power and unbalance caused by various loads in distribution system. An evaluation of three different methods has been made to derive reference currents for a DSTATCOM...

[texts]25. Eng Tuning Of A Novel Feedback First Order Compensator Galal A. Hassaan - GALAL A. HASSAAN
Compensators are used in place of classical PID controllers for possible achievement of better performance. Highly oscillating processes require more effort in selecting proper controllers or compensators. In this work a novel compensator based on a series proportional controller and a feedback lag-lead compensator is proposed and applied to control a process having 85 % overshoot and about 6 seconds settling time...

[texts]6. Tuning Of A Lead.full
Lag-lead compensators are well known in automatic control engineering. They have 4 parameters to be adjusted (tuned) for proper operation. The frequency response of the control system or the root locus plot are traditionally used totune the compensator in a lengthy procedure. A first order with an integrator process in a unity feedback loop of 67.3 % maximum overshoot and 12  seconds settling time is controlled using a lag-lead compensator (through  simulation)...

[texts]A Novel Compensating Technique for Power Factor Improvement in Power Electronic Systems
Power electronics systems are non-linear systems, which consume more reactive power and also the loads they feed are mostly inductive loads which leads to a poor power factor. Various compensation techniques are available to bring the power factor nearer to unity. In this paper, a novel compensator is proposed, where in-phase and quadrature components of the supply current are vector-controlled. Implementation of this compensator in a power electronic system operating with a very poor power fact...

For more detail & Live Demo of Auto Profit robot { Cost – 45 US dollars.} . Its really amazing Skype ID – shahid.mycco email yousaf.shahid@gmail.com Trading robot Auto-Profit is fully automatic and has a high yield and productivity. Despite its high level of profitability, the system has reduced risks. Advisor (robot trading system) Auto-Profit is the latest version of the most stable and trusted adviser time for a profitable multi-currency trading in the forex market. An expert can use both to trade any of the available tools of the trade (currency pairs, CFD, metals, etc.) The benefit of the adviser is fully analyzing the current state of the market and make informed decisions, where b is not the price has gone. Auto-Profit easily adapts to any currency pair and works perfectly for all time periods. In the process, Adviser monitors the open foreign exchange position for each currency to minimize foreign exchange risks. Due to the fact that trade is conducted in several directions, the adviser does not fixate on one accompanied by an open position and opens the parallel position on other instruments, thus compensating for the risks and reducing the possibility of a large almost to zero drawdown. Advisor is not a Pipsovschik, and his work has no claims on the part of any of the well-known brokers. Since the EA trades at once in both directions, its profitability in times greater than the profitability of their predecessors. Auto-Profit Advisor is a new generation, are not to be restricted to trade only with one or more currency pairs, and use the full potential of the market and the whole range of possible tools of the trade! The main advantages of Auto-profit 2.1 over previous versions :An updated analysis of the logic of using trading volume of all transactions, the market expects an imbalance of lots and allows it to trade. Has the function of monitoring a minimum level of free capital account, which increases the stability of the adviser to the long-term trend movements. In the Auto profit v.2.1 laid down the same principle of trade, and the Auto profit v.2.0, but the new version has a number of significant amendments to the trading algorithm and expanded a number of options available to the user for possible changes: 1. This version introduced the parameter Exit_mode - specifies the mode of the program, it may be an ordinary trade regime, or mode of Exit - exit the market in which the Adviser, in its closing order logic, more they will not open until you he does not allow it. The function is useful when planning to stop the adviser, for example, to remove the profit. 2. It is possible to install a fixed initial sales lot. 3. program does not use the pending orders. 4. We use virtual trading levels of the grid (marked horizon. lines on the chart), with achievement of which the program is making in its inherent logic of the action. 5. algorithm consists of three logical parts: - the basic logic - when net sales are normal. - support - when the error condition occurs, it closes the warrants using the average over the volume with the total trading results or trallingstopa grid to normal. - trade only BUY / SELL - Control logic - ensures that while the core logic (TS standard) for all orders was put TP or SL. 6. program can trade in three layers, the inclusion of each additional layer depends on the number of orders of the previous layer, or layer is directly connected as a compensator imbalance of trade in the previous layer - the protective function - relationship is set in the properties. 7. Distance to install the following order (hSetky) may be dependent on the number of orders can uvlichivatsya or decrease, be constant. 8. Program continues to trade in any situation, for it is not afraid of interruptions in connection with the server broker, gaps, turn off the terminal and other abnormal situations. After turning the program recognizes their orders and, as applied to trade virtual levels, there is an auxiliary logic of the program over time, she recovered to work normally. 9. All dependencies and parameters of the program the user can modify its properties in the manual describes each parameter of the program. There is a selection of OE files. 10. program analyzes the imbalance of trade items each layer separately, and the overall imbalance of orders, depending on the trade that can be sent for each layer of the trade that would secure the trade. 11. program uses analysis of the available funds account, comparing it with the control level. And if the available funds are less dangerous border, you can specify in the settings, the adviser is blocking layer is the most dangerous trade, and continues to work less bulky. This allows you to increase the trading price range adviser. What have to do Step 1.
